There will be apertures 2 inthe ends of the shuttle to admit air, and the head or butt piece 3 ofthe bobbin will be clamped firmly when in place between shoulders 4-and5 on the shuttle-body and end piece, respectively. All of the abovefeatures are shown in our before-mentioned application butin the presentconstruction the shuttle has in its crown an aperture 6, which comesunder the transparent plate 15 when the shuttle enters the shut tle-boxand permits the weaver to inspect the bobbin and note the condition ofthe weft thereon. I I

H The shuttle illustrated in Figs. 3, 4, 6, and 7 is represented ascylindrical, and if made in this form it should be provided with aballast 7 in the nature of a strip of lead, for example, at its bottomor low side to prevent the shut tle from turning axially while passingthrough the shed. Obviously, and in some cases preferabl y, the shuttlemay be of rectangular crosssection, (the common form,) as seen in Fig.8. We do not limit ourselves at all as to the crosssectional contour ofthe shuttle and box.

The means whereby the exhaustion of the weft on the bobbin orweft-holder in the shuttle controls the loom stopping mechanism and thesaid mechanism will now be described.

In the outer end of the shuttle-box 7c and alined therewith is mounted aslide-rod 8, which may have a head9, Figs. 1, 2, and 2, in the interiorof the box and in the prolongation of the path of the entering shuttle.This rod is coupled exteriorly of the box to one arm of a lever 10, theother arm of which is coupled to a swing-rod 11, the free end of.

which has a sliding bearing in an arm or branch 12 on the knock-offlever d. Normally the shuttle y enters the box it only to the extentseen in Fig. 2, as the cushion in the box formed by the incarcerated airtherein checks its momentum and arrests it; but when the weft on thebobbin is nearly exhausted this exhaustion of the weft opens apasage-way through the shuttle for the incarcerated air by means thatwill be hereinafter explained. The resistance of the air to the entry ofthe shuttle into the box is thus reduced, and the shuttle enteringfarther into the box (see Fig. 2 impinges on the head or end of theslide-rod 8 and drives this rod outward. This movement of the rod 8,acting.

through the lever 10, has the effect to move the swing-rod l1 endwise(see dotted linesin Fig. 1) until its head or free endis protruded intothe path of a tappet 13 on a going part of the loom, as on the lay orreed, for example. When the lay next heats up, the tappet 13 impinges onthis protruding end of the rod 11 and through it and the arm 12 shiftsthe knock-off lever d, frees the shipper-lever f, and allows the latterto stop the loom. As the rod 11 swings, however, under the influence ofthe tappet 13 a stud or stud-roller 14 thereon encounters the inclinedface of a lug 15 on the bracket 0 and draws in or back the rod 11,returning it to its normal or first position. This means of returningthe rods 8 and 11 to their normal position is important, as it is notconvenient in this construction to employ a spring for the purpose ofretracting the parts.

Referring now to Figs. 4 to 7, the weft-control in the shuttle will bedescribed. As before stated, the air can enter the shuttle at either endthereof through the apertures 2 therein; but the full bobbin orweft-holder acts as a partition between the apertures at the oppositeends of the shuttle and prevents the air from passing through it.However, when the weft is nearly exhausted from the bobbin a passage orpassages are opened through the shuttle. This is done, as herein shown,by making the butt of the shuttle hol low and forming in its wall slotsor apertures 16, (one or more,) these apertures being each provided witha flat spring closer 17, which normally or when the bobbin is nearlyexhausted of weft springs outward, as seen in Fig. 5, by its ownresiliency and opens the aperture 16; but when the weft is wound on thebobbin it presses in the springs, so that they practically close theapertures, as seen in Fig. 4. In order that the springs may open quicklyduring one pick of the shuttle, it is preferred to form a hump 18 on thespring for the weft to bear on, so thatwhen the latter is removed fromthis hump the spring will be free to spring outward,as seen in Fig. 5.Some Weft will still remain between this hump and the flanged butt ofthe bobbin, so that no defect will be produced in the cloth by the totalexhaustion of the weft when the loom stops. There may be, of course,stop mechanism provided, such as that we have described, at each side ofthe loom; but. it will suffice to apply it to one side of the loom. thislatter case the shuttle should be provided with a check-valve to preventair from passing through the shuttle in but one direction. The shuttlein this case should always enter the box 70, where the stop mechanism issituated, with that end thereof foremost which permits the air to passback through the check-valve. The reason for this is fully explained inour pending application, Serial No. 735,647, filed November 3, 1.899,and in Figs. 4 and 7 we have shown the same form of check-valve as thatillustrated in our said pending application--that is to say, anapertured partition 19 in the shuttle and flexible valves 20, of rubber,soft leather, or the like, fixed to one face thereof.

Figs. 9 and 10 show a construction where the shuttle-box kis mounted onand vibrates with the lay, and they show the air supplied to the box bya rocking or vibrating upright pipe 21, coupled at its upper end to thebox and at its lower end to the pipe 0, with an oscillating couplingaxially aiined with the swing-rail, which forms the center of vibrationof the lay.

In the principal views the stopping mechanism is controlled by the tipof the entering shuttle driving back a rod 8 alined therewith; but wemay as well employ adevice substantially similar to that shown in oursaid pending application, Serial No. 735,647, wherein the shuttle actswith a wedging action. In this construction (illustrated in Fig. 9)there is a spring-arm 22, mounted in the shuttle box, so as to bepressed or wedged outward by the incoming exhausted shuttle, and a beakon this spring, which plays through the wall of the ShHLtlG'IJOX, bearson one arm of an elbow-lever 23, mounted on the lay or box and providedwith a retracting-spring 24. To the other arm of this lever is coupled asliderod 25, mounted in suitable guidebearings on' the lay. When theshuttle presses outward the spring-arm 22, the slide-rod 25 isprotruded, so that when the lay heats up the end thereof will encounterthe arm 12 on the knock-off leverand operate the latter to stop theloom. By coupling the spring-arm 22, through its beak, to the arm of theelbowlever the spring 2a may be dispensed with, as the spring-arm itselfwill then retract the parts as soon as the empty shuttle is removed fromthe box. I

It is desirable in wide looms, where the shuttle requires some time totravel through the shed from one box to the other, and par ticularlyalso in looms where the shuttleboxes do not vibrate with the lay, toprovide a mechanism for operating the vibrating parts forming theraceway which will allow the same to dwell or rest during the travel ofthe shuttle through the shed. In looms as ordinarily constructed thevibration of the lay is effected with cranks, and there being no rest ordwell the lay moves back beyond the picking-point aft-er the pickingstroke and comes up again to that point to receive the shuttle. In Fig.10 we have shown means for producing such a dwell or rest at thepickingpoint, said means comprising, as a sub stitute for the ordinaryconnecting-rods and cranks, a grooved side cam 26 on the ordinarycrank-shaft 27 of the loom, said cam having in it a cam-groove which isengaged by a stud-roller 28 on a connecting-rod 29, coupled to thelay-sword i and slotted to embrace the boss of the cam 26. A properportion 30 of the groove in the cam will be made concentric with theshaft 27, so that during that portion of the rotation of said' shaftwhile the shuttle is traversing the warp-shed the lay will be at rest.

raceway is especially useful in a loom where the shuttle or weft-carrieris driven or picked by a compressed aeriform fluid, as this mode ofdriving the shuttle is especially adapted to quick-running looms,wherethe to-and-fro motions of the reed are very rapid, as well as those ofthe shuttle.

By providing the shuttle-box with a trans parent cover-plate and theshuttle with an opening in its top the weaver may see the bobbin atintervals and note the condition of the weft thereon; but in a certainclass of weaving where great rapidity is essential it is difficult underany circumstances for the weaver to note when the shuttle requires a newsupply of weft, and this invention provides for stopping the loom in anycase before the weft is entirely exhausted, so that the weaver is notrequired to note the condition of the weft. When a weft-thread breaks,the usual weft-fork and weft-hammer mechanism found on most looms (andnot herein illustrated) will act to stop the loom.

In case of a shuttle having to be driven out of the box 76 after theloom shall have stopped this may be effected by means of a jet or chargeof compressed air from the reservoirZ (or other source) through asuitable pipe 31, which forms a bypass to the pipe 0 or the shuttle-boxabout the valves 19 and g. This pipe will be provided with a suitablecontrol ling valve or cook 32.

Our pneumatic device for controlling the times of operation of theloom-stopping m echanism-that is to say, the vent orpassage for air inthe Weft-carrier or shuttle, which is opened by the exhaustion orsubstantial exhaustion of the weft or filling thereinrequires a specialform of shuttle box or cell, and this form of box or cell is alsoadapted for use where compressed air is employed for picking theshuttle, and hence we have shown in the drawings these two featurescombined; butthe pneu matic controlling device is adapted for operationin any loom having a suitable shuttle box or cell wherein the air willbe incarcerated by the entry of the shuttle therein. In order that thepneumatic control shall be effective, the shuttle must enter the boxsomewhat in the manner of a piston in a cylinder. Being the first, as webelieve, in this field of invention, we claim, broadly, and wouldconsider as coming within the scope of our invention, a mechanism forstopping the loom, combined with pneumatic means controlling the timesof operation of said mechanism, and also such a stopping mechanism combined with means for applyingan aeriform fluid to pick or drive theshuttle, and pneumatic means at the shutl' le'box for controlling thetimes of operation of said mechanism.

By exhaustion or substantial exhaustion of the weft-or fillingin theweft-carrier in play we mean either the entire denudation of the weftholder or such degree of denudation thereof as will allow the shuttle orweft carrier to perform its functions as described.

IIO

a 65ml By'a shuttle or weft-carrier we mean that which carries the weftor filling or yarn through the warp-shed in the process of weaving, andby bobbin or weft-holder we mean that device in the shuttle on which iswound the weft or fllling.- This device or part is variously called abobbin, a spindle, a cop, 850. Where there is a spindle, the cop or allcop will usually be slipped thereon.

In Figs. 1, 2, and 9 we have shown a protection-finger 33 of a. knownform adapted to operate in connection with the usual coacting mechanismto stop the loom in case a shuttle does not enter the box as it should.

We have shown lateral apertures in the receiving end of the shuttle-boxto effect the lateral deflection of the charge of air which picks theshuttle or a portion thereof, so that it may not follow the shuttle intothe warps of the loom; but we do not limit ourselves to this particulardeflecting means. For example, our pending application, Serial No.

9,842, filed March 23, 1900, illustrates another deflecting means.
